                GridView2.Visible.Equals(true);

        }

Answer 1

You need to assign false to the visible property. Currently you are comparing it, if it equals false. Do it like:

GridView2.Visible = false;

Your current code returns a bool value, it doesn’t set the Visible property of the gridview

GridView2.Visible.Equals(false);

The above line from your code compares if the GridView2.Visible property is set to false. It doesn’t update the Visible property of the gridview.

Similarly to make the Grid View visible set it to true like:

GridView2.Visible = true;
